, GATE LOCK .I ohnLainach, Billings, Mont. Application July 29,1944seria1N6. 547,178 claims (01.;298-23) l l My invention relates, ingeneral, to the art of closure fasteners and it especially relates to`end gate locks for dump vehicles.

Primarily the invention has foranfobject t0.

provide a simplerugged devcefor securing a hingedclosure'to a body in'such 'manner thatv movement between the closure and the body at thelocked area will be effectively prevented. i

A further object is to provide end gate locks for a dump type vehicle,for holding the` free edge of a hinged gate dirmly secured to each sidewall of the vehicle so that the end ygate will serve as a cross bracebetween the upper parts of the side walls. n

A still further object is to lprovide a fastener that can be' used inallplaces where a fastener employed, it being designed .y

of its kind can be particularly for use upon curely in place regardlessof the amount of material within the truck whichmay press'against it (i.e. the pressure of the material will notl sill are secured at 4E, hollowposts 4 having flanges 5`which are welded to the sides 3.`

, of thev same.

Metal plates B are welded to the upper yrear ends ofthe wall 3 and theoutwardy angled flange 3a These plates 6 (one at each side of thevehicle),have holes 'I for the reception of dowel pins I'I carried bystrikerl plates I5, which plates are securely welded to the uppercorners of lthe door 8; The door 8 is dished, as at 9,'to t within thebody'opening and it has a marginal iiange I0 as shown in Figs. 1 and 3.

The door to the sill I, as for instance by hinges whose straps I I arelooped back as at I2 and secured at AI I a to the door. The otherelements I4 of the `hinges carry pins I3 that pass through the por-Again it" is an object to provide a means for securing an end gate inclosed position in such manner that it will not rattle.

Other objects will in part -be obvious andin part be pointed outhereinafter. To the attainment of the aforesaid objects and ends theinvention also resides in those novel details of construction,combinations and arrangements of parts all of which will hereinafterfirst be fully described and then be specifically pointed out in theappended claims, reference being hadto the ,accompanying drawingin-which:

Fig. 1 is a rear elevation of a portion of a vehicle with an end gate,showing one of the two locks employed to secure the gate in closedposition.

Fig. 2 is a detail elevation same looking in the Fig. 1.

Fig. 3 is a detail horizontal section on the Iline A3-3ofFig. -b n Fig.4 is a detail rear elevation showing the angle-bracket which carries thelocking device.

In the drawing in Which like numerals of reference indicate like partsin all the gures, I represents the rear cross sill ofthe vehicle, 2 thefloor and 3 the side walls. In the structure illustrated the side walls3 and thedoor 8 are constructed of sheet metal. To the ends of thev of aportion of the direction of the arrow in n tions I2 of the straps asindicated in Fig. 1. 'Ihe striker plates I5 each have their outer edgesbent at approximately right angles as at I6 for a pulpose presently toappear.

At each side of the vehicle and adjacent but in front of the posts 4,there are angle-brackets i8, secured at I9 to the sides 3. Thesebrackets I 8 have holes 20 for the passageof eye-bolts 2l. Pivoted at 23to the eyes of the bolts 2I of angle links 22. The angled ends of .theselinks, when the gate is locked, project over the ends IEy of the platesI5 and carry pivots25 for the When in the locking position `(Figs. l to3), the pivot axis 25 of the device lies directly to the rear of thedowel I'Ir (see Fig. 3),

Awhile the pivot 23 lies to the outer side of the same.

Each locking lever 24 has a nose 2B which engages the plate I5 at apoint between pivotsl 25 and 23 and when locked, engages the lip formedby the bent portion I5 of the plate. The long arm of the lever 24, inthe locked position lies flat against the plate I5.

Coil springs 21 on the forward portions of the eye-bolts 2|, and lockednuts 28 serve to supplyl the required tension in the direction of theparallel arrows in Fig. 3 to keep the gate locked.

To unlock the gate the levers 24 at each side ofthe gate are pulled inthe outward direction (see curved arrow at in Fig. 3), until the pivots25 pass to positions between noses 26 and pivots 23 (noses 26 lacting asthe fulcrums) whereupon the springs 21 will pull the links against theangle-brackets I8 as stops. The gate 8 may now be swung down on itshinges.

From the foregoing description taken in connection with the accompanyingdrawing it is thought the construction, operation and advan- 8, of sheetmetal, is suitably hinged are pairs f tages of my invention will beclear to those skilled in the art.

What I claim is:

l. In combination with a body having a transverse wall and two sidewalls, and a closure hingedly connected to said transverse wall andadapted to t between said side walls when in closed position:dowel-carrying plates rigidly secured to opposite sides of said closureat places remote from the hinge connection and overlapping said sidewalls; plates secured to said side Walls to lie normal thereto; saidlast named plates having holes to receive said dowel pins; and latchesmounted on the body sides and having means to engage the dowel-carryingplates to hold the dowels in the said holes.

2. In combination Witha body having a transverse wall and two sideWalls, and a closure hingedly connected to said transverse wall andadapted to t between said side walls when in closed position;dowel-carrying plates rigidly secured to opposite sides of said closureat places remote from the hinge connection and overlapping said sidewalls; plates secured to said side walls to lie normal thereto; saidlast named plates having holes to receive said doWel pins; bracketssecured to the said sides; spring loaded I bolts mounted in saidbrackets; said dowel-carrying plates having lips and levers having toesfor en-` gaging said lips; angle links pivoted to said I bolts and tosaid levers and extending over the ends of said walls and closure whenin locked position by virtue ofall of which the dowels will be held intheir holes and the closure will constitute a cross brace between theside walls.

3. In combination with a body having a transe verse wall and two sidewalls, and a closure hingedly connected to said transverse wall andadapted to fit between said side walls when in closed position:dowel-carrying plates rigidly secured to opposite sides of said closureat places remote from the hinge connection and overlapping said sidewalls; plates secured to said side walls to lie normal thereto; saidlast named plates having holes to receive said dowel pins; bracketssecured to the said sides; spring loaded I bolts mounted in saidbrackets and disposed parallelly to said sides in the longitudinaldirection of the same; said dowel-carrying plates having lips and levershaving toes for engaging said lips; angle links pivoted to said I boltsand to said levers and extending over the ends of said Walls and closurewhen in locked position by virtue of all of which the dowels will beheld in their holes and the closure will constitute a cross bracebetween theY side walls.
